Camels are large animals living in dry areas. There are two species of camels; the Arabian camel with a single hump(驼背) from the dry desert areas of West Asia, and the Bactrian camel with two humps from Central and East Asia. Camels are over 7 feet tall and weigh over 1,600 pounds. They will live up to 40 to 50 years. Most camels are domesticated(驯化) and fed by people. Camels are plant-eaters.
Camels are very strong animals with wide, padded feet. They have thick leathery pads on their knees and chest. Camels have nostrils(鼻孔) that can open and close, protecting them from the desert environment. Bushy eyebrows and two rows of long eyelashes protect their eyes from sand. Their mouth is extremely tough, allowing camels to eat thorny(带刺的) desert plants. Their widened feet help them move without sinking into the sand. Their thick coats reflect sunlight, and also protect them from the intense heat from desert sand. Their long legs help by keeping them further from the hot ground.
Camels can go without food and water for 3 to 4 days. They do not store water in their humps as is commonly believed.The humps are actually a container of fat. Camels are incredibly well-adapted to their environment. When conditions heat up, camels can increase their own body temperature, which prevents sweating and therefore water loss. They may not sweat at all during the day.
Camels are sometimes called “ships of the desert” because people ride them around the hot, dry deserts of the world. However, the number of camels is becoming smaller for various reasons.
1.According to the passage, camels usually live in ________.
A. Asia B. Africa
C. America D. Australia
2.Paragraph 2 is mainly about ________.
A. camels are useful animals
B. camels are clever animals
C. camels’ body structure and function
D. camels’ characteristics and habits
3.The reason why camels lose little water in deserts is that they ________.
A. get water from green foods
B. can adjust their temperature
C. store enough water in the humps
D. can manage without water
4.What will the author probably talk about following the last paragraph?
A. Ways to protect camels.
B. Habitats of camels.
C. Reasons for raising camels.
D. Functions of camels.

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. It is like a person jumping over about 30,48. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.
1.The earliest frogs lived about ________ million years ago.
A. 20 B. 30 C. 50 D. 190
2.The Gold Frog is one of the ________ frogs on the earth.
A. smallest B. biggest C. strongest D. weakest
3.________ can jump over 2m.
A. The Goliath Frog B. The Common Wood Frog
C. The Poison Frog D. The Australian Rocket Frog

Camels are well known for their ability to survive the hot and dry conditions of the desert,but a study suggests they once grew well in colder climates. Scientists have found fossilized(化石) parts of a leg bone belonging to a giant camel that lived in the forests of Canada's High Arctic about 3.5million years ago.
The research is published in the journal Nature Communication. Dr. Mike Buckley, an author of the paper from the university of Manchester, said, "What's special about this story is that this is the northernmost evidence of camels. "The area was warmer than today 3.5 million years ago, but the ancient giant camels would have had to face long and bitter winter, with temperatures below freezing. There would have been snowstorms and about six months of darkness.
While scientists have known for some time that camels existed in North America, with the earliest creatures dating to about 45 million years ago, they were astonished to find a species at such a latitude(纬度).
Over the course of three investigations, which began in 2006,researchers from the Canadian Museum of Nature collected 30 pieces of the leg bone from Ellesmere Island in Canada.
Their size suggested that the animal was about 30% larger than today's camels, measuring about 2.7m from foot to shoulder. Despite its size, the researchers believe it would have been similar in appearance, although it probably had a thicker coat to stay warm.
To investigate further, the team took the protein found in the bone from the fossils and modern animals. Dr. Buckley said, "The results tell us that it is a direct ancestor of modern camels. "
He said the findings provided a new insight into the evolution of this animal. "It suggests that many of the adaptations(适应) that we currently think of, in terms of camels being adapted to warm desert-like environments, could have actually originated through adaptation to quite the opposite cold, bitter environments. Camels 'humps(峰)which store fat could help get through an Arctic six-month winter. Their large eyes would have helped them to see in the low light,and their wide,flat feet would have been just as useful for walking on snow as they are on sand,"he explained.
1.What surprised the scientists when they found the giant camel fossils? ___
A.Their size. B.Their shape.
C.Their place. D.Their number.
2.According to the text, the ancient giant camels___.
A.could date to about 45million years ago
B.struggled to survive in severe conditions
C.were the first ancestors of modern camels
D.lived in an environment without light
3.Compared with modern camels, the ancient giant camels___.
A.were much taller
B.had more humps
C.were slightly stronger
D.had thinner coat
4.We can infer from what Dr. Buckley said that___.
A.giant camels had special adaptations for polar life
B.cold environments prevented giant camels developing
C.the cause of the extinction of giant camels remains unknown
D.the hard climates forced giant camels to adapt to warm environments

When nature is left alone, a balance is reached among the animals and plants living in one area. But when man starts his work in nature, the balance is likely to be destroyed. He grows a crop and takes it away to eat ;then there are no dead leaves to fall on the ground, holding water while it sinks into the surface, or decaying (腐烂) and adding humus (腐殖质) to the soil. Unless a farmer acts with knowledge and skill, he is therefore most likely to make the land poorer. To take the place of the useful matter in the crops that he removes, he uses some kind of fertilizer (肥料). Chemical fertilizers are of great help, but the waste products of animals and decaying remains of plants should also be put on the land. In some places, it is a habit to burn waste material lying about, but such burning destroys the useful matter in the dead plants. Although the ashes that are left are valuable when put on the land, a better practice is to bury the waste so that it decays and increases the humus in the soil.
In the past, when the world population was much lower than it is now, a man had little difficulty in ordinary times in growing the food that was needed. When a field had been used some years and had become tired, the farmer could move to another place. The tired land then slowly recovered. By and by grasses and other plants would appear on it and its productive power would slowly return to normal through their decay. But nature, left alone, would take a long time to bring back the land to its former state; the length of time required would depend on local conditions, but it might well be ten years.
It is a bad practice to grow the same crop in a field year after year. If the crop is changed, the land will suffer less because it is treated and used in a different way. Different plants have different effects on the soil. Therefore, a change of crop will do less harm than the growing of the same crop year after year and a regular change to grass will do good to the soil. Much will therefore be gained if different crops are grown one after another, a method known as the rotation (轮作) of crops.
1.According to the passage, the land will become poorer ( )
A. if all the dead leaves are cleared away B. if the humus is increased after the harvest
C. if dead leaves decay in the soil by themselves D. if waste plant material lying about is buried
2.We can learn from the passage that the tired land has slowly recovered ( )
A. when grasses and other plants appear again
B. when the treatment is given by nature alone
C. after new grasses and other plants have decayed again
D. after nature has been left alone for several months
3.A modern farmer can hardly move to another place as he did before because ( )
A. the productive power of a new field isn't higher than that of an old one
B. there are few free fields left for him to do farming
C. it takes a farmer more than ten years to start farming in a new field
D. there will be too many grasses in a new field to grow crops
4.It is most likely that the author will go on to ( ) in the paragraph following the passage above.
A. introduce other methods of planting crops B. deal with how to prevent land getting tired
C. start another topic of how to make use of land D. further explain what the rotation of crops is
